Is this as simple as it gets? Perhaps there is another 'path' I could have taken which would have let me get it even simpler yet I have tried and tried and can't figure it out. Care to lend a helping hand?

Much appreciated,

I should mention that I am going to make it a circuit. Its second nature for me to try and get things into brackets and even though that may not make the circuit any simpler I tend to do it anyway.
